Which is the largest galaxy in universe?
IC 1101
The biggest known galaxy is IC 1101, which is 50 times the Milky Way’s size and about 2,000 times more massive. It is about 5.5 million light-years across. Nebulas, or vast clouds of gas, also have impressively large sizes.
Which is the second largest galaxy in the universe?
The three largest members of the group are our Milky Way (second-biggest), the Andromeda galaxy (biggest), and the Triangulum Galaxy. The other galaxies in the Local Group are dwarf galaxies, and they’re mostly clustered around the three larger galaxies.
What describes an elliptical galaxy?
An elliptical galaxy is a type of galaxy with an approximately ellipsoidal shape and a smooth, nearly featureless image. They are preferentially found close to the centers of galaxy clusters. Elliptical galaxies range in size from tens of millions to over one hundred trillion stars.
What is the closest galaxy to the Milky Way?
the Andromeda galaxy
Although several dozen minor galaxies lie closer to our Milky Way, the Andromeda galaxy is the closest large spiral galaxy to ours. Excluding the Large and Small Magellanic Clouds, visible from Earth’s Southern Hemisphere, the Andromeda galaxy is the brightest external galaxy you can see.
What is bigger than a galaxy?
From largest to smallest they are: Universe, galaxy, solar system, star, planet, moon and asteroid.
What is our galactic supercluster?
The Laniakea Supercluster is the supercluster that contains the Virgo Cluster, Local Group, and by extension on the latter, our galaxy; the Milky Way.
Is Hercules a galaxy?
Several other elliptical and spiral galaxies that are visible in the Hubble data may be members of a cluster of galaxies. Hercules A is by far the brightest and most massive galaxy in the cluster.
What are 3 facts about elliptical galaxies?
Elliptical galaxies have a large range of sizes. The largest elliptical galaxies can be over a million light-years in diameter. The smallest “dwarf elliptical” galaxies are less than one-tenth the size of the Milky Way! Elliptical galaxies have very little gas and dust.
Why is it called elliptical galaxy?
One of the most common types are elliptical galaxies, named because they have an ellipsoidal (or egg) shape, and a smooth, almost featureless appearance. Elliptical galaxies are usually large, containing hundreds of millions to trillions of stars. The biggest galaxies in the Universe are elliptical galaxies.
How big is the IC 10 dwarf galaxy?
IC 10 is an irregular dwarf galaxy with an H II nucleus of about 5,000 light-years across, located some 2.2 million light-years away in the northern constellation Cassiopeia and it is approaching the Milky Way at approximately 350 kilometers per second. IC 10 is an outlying member of the Local Group of galaxies and belongs to the M31 subgroup.
How old is the galaxy IC 1011 in years?
IC 1011. IC 1011 is a compact elliptical galaxy with apparent magnitude of 14.7, and with a redshift of z=0.02564 (SIMBAD) or 0.025703 (NASA), yielding a distance of 100 to 120 Megaparsecs. Its light has taken 349.5 million years to travel to Earth. IC 1011’s calculated age is approximately 12.95 billion years.
What kind of stars are in IC 10?
Compared to other Local Group galaxies, IC 10 has a large population of newly formed stars that are massive and intrinsically very bright, including a luminous X-ray binary star system that contains a black hole. Although considerably smaller the Small Magellanic Cloud (SMC) IC 10 has a similar luminosity.
Who was the first person to discover IC 10?
IC 10 is an irregular galaxy in the constellation Cassiopeia. It was discovered by Lewis Swift in 1887 and in 1935 Nicholas Mayall became the first to suggest that the object is extragalactic.
